"Applause (Latin applaudere, to strike upon, clap) is primarily the expression of approval by the act of clapping, or striking the palms of the hands together, in order to create noise; generally any expression of approval. Audiences are usually expected to applaud after a performance, such as a musical concert, speech, or play. Applause should not be confused to clapping with the rhythm of a song but should have a random, sporadic matter to it."
Hjorten manipulates the idea behind applause by re-arranging situations we are used to, and finds rhythm where none is expected. The sound sources are treated and forced into doing what he wants, creating an experimental and minimalistic picture by hand.
This is what you're waiting for, what comes after the short silence when you've stopped. A simple act that doesn't take much effort, but can mean so much. The smattering sound that echoes through a hall flows to the small pub where people stand up to cheer.
